【摘要】：我國股權(quán)分置改革的實施,推動了上市公司新一輪并購高潮的出現(xiàn),也促進了跨國并購的蓬勃發(fā)展。傳統(tǒng)金融理論假設(shè)市場有效、投資者和管理者完全理性,對并購及跨國并購的一些績效異常情況缺乏解釋力。因此,本文基于行為公司金融學(xué)的研究視角,將投資者情緒與管理者過度自信理論相結(jié)合,分析了投資者情緒、管理者過度自信對跨國并購績效的影響及其影響路徑。本文的研究成果豐富了行為金融學(xué)對跨國并購績效影響的研究,也為我國上市公司改善公司治理機制、建立科學(xué)的投資決策機制以及保護跨國并購活動中股東利益提供了實證支持。本文以我國資本市場上存在投資者非理性和管理者非理性,且這種非理性易引發(fā)非理性投資為背景,回顧了學(xué)者們關(guān)于投資者情緒、管理者過度自信對并購及并購績效的有關(guān)研究。然后依據(jù)噪聲交易理論、認(rèn)知失調(diào)理論、情緒泛化假說及自大假說等理論,梳理了投資者情緒和管理者過度自信影響企業(yè)跨國并購績效、投資者情緒影響管理者過度自信的作用機理,并提出了相關(guān)假設(shè),確定了相關(guān)變量的衡量方法。之后建立了回歸模型來檢驗相關(guān)假設(shè),并得出了研究結(jié)論。最后從行為金融學(xué)的視角上,對如何更好的提升跨國并購績效以及如何識別投資者和管理者非理性提出針對性的建議,為我國企業(yè)更好的完成跨國并購活動提供了支持。在本文的實證分析中,以2013年間在滬深A(yù)股市場上的33起跨國并購事件為樣本,將跨國并購績效分為短期績效和長期績效,分別檢驗了投資者情緒對管理者過度自信、跨國并購績效的影響;之后將投資者情緒與管理者過度自信相結(jié)合,檢驗了管理者過度自信在投資者情緒和跨國并購績效之間的中介效應(yīng)。本文研究發(fā)現(xiàn),管理者過度自信與投資者情緒正相關(guān);跨國并購績效與投資者情緒負(fù)相關(guān);管理者過度自信在投資者情緒和跨國并購績效之間存在部分中介作用。本文的研究內(nèi)容及框架共分為五部分:緒論、理論分析與研究假設(shè)、研究設(shè)計、實證分析與結(jié)果和結(jié)論與建議。在緒論中介紹了研究背景,提出了要研究的問題,并闡述了本研究的理論與現(xiàn)實意義;然后,對投資者情緒、管理者過度自信與并購績效進行了相關(guān)的文獻回顧與評述;最后提出了本文的研究思路、研究方法、研究內(nèi)容、基本框架和創(chuàng)新點。在理論分析與研究假設(shè)中對相關(guān)變量的概念進行了界定,并介紹和確定了變量的衡量方法;然后梳理了投資者情緒及管理者過度自信的相關(guān)理論;并依據(jù)這些理論分析了投資者情緒、管理者過度自信與跨國并購績效三者之間的關(guān)系,提出了研究假設(shè),為下文的實證提供鋪墊。在研究設(shè)計中首先介紹了跨國并購樣本的選取、數(shù)據(jù)的來源、所需的變量及其定義,并在此基礎(chǔ)上,提出了實證研究的模型,并對模型進行了剖析。實證分析與結(jié)果中首先介紹了跨國并購短期和長期績效的計算;之后進行了描述性統(tǒng)計分析;然后分為短期績效和長期績效,分別進行了相關(guān)性分析,并回歸檢驗了投資者情緒對管理者過度自信的作用、投資者情緒對跨國并購績效的作用,并探討了管理者過度自信在投資者情緒與跨國并購績效關(guān)系中的中介作用;最后進行了穩(wěn)健性檢驗。結(jié)論與建議章節(jié)中首先總結(jié)了研究結(jié)論;之后對本文的研究結(jié)論進行了相關(guān)討論,提出了一些針對性意見;最后分析和討論了本研究的局限性,并對未來研究的方向進行了展望。
